These parts are not furtherdetailedas the details thereof form no partgof my present The :bed. 2'is formed of a pair of plates 5a 1 1 and 15 having telescoping flangeslGand 1' 16 at their edges. The plates are held in spacedrelation by theshouldered spacing spools 17; @Thespools also constitute,sup-, ports forthe posts 18 p a t a '1 60 ;These posts are provided with heads'19 attheir upper ends and are shouldered at 20 to 511121111311, nested Withinthe cam member23 The posts arealso provided with clamping nut 24:; belowthe bed sothat the cam members areclampedupon thebed. v These-cammembers in the-emhodimentfillustratecl' are cupped stampings,theirflanges o The bed is provided with holes 25 Which are engaged bylugs 26 on the outercam members, theseholes being positioned in theupper plateof the bed .to properly position a the cams. To'position theinner and outer cam-s relative to each other, the outercamsare providedwith recesses. 27 and the inner cam. member with lugs 28, these lugs,and, I

pairs'of camsrelative to each other. H Byflthis arrangement the outercams may all be formed by one die,,that is, they are all alike, and theinner cams are also all alike, v 3 I so it is merely a matter ofpositioning them In the: embodiment illustrated I provide a relative toeach other on thebed to properly control, the coacting mechanism a'ndthey are clamped in place bythe posts. The clamp members 21 also serveas end thrust members for the rotary heads designated generally by thenumeral 29. These heads-consist of hubs 30, top pl'ates 31 and bottomplates 32 held in properly spaced relation by the spacing sleeves38arranged bet-Weenthe plateson thehub. The gears 34 are also mounted onthe hubs and .areheld in' properly spaced relation to the bottom plate32'by the rings 35 and rings 36 arranged below the gears- The gears arearranged in meshing relation.
